Objectives:We investigated and studied the incidence of depression in the wake of cerebral infarction Methods:Self-rating Depression Scale (SDS) and Hamilton Depression Scale (HAND) were evaluated and tested among 210 patients of cerebral infarction, and at the same time a contrast was made among 50 normal persons At the patients were divided into two groups, one suffered from depression and the other not suffered from depression Then they were compared Results:The depressive mood of the patients of cerebral infarction was obviously higher than those of normal group In this thesis, the incidence of cerebral infarction with depression is 58% The incidence of this disease was higher among the patients with depression history, females and those who lived apart from one's family Conclusions:The incidence of cerebral infarction with depression is comparatively high, so it should be taken seriously by the clinical doctors

Objective:To study the protective effect of glucagon-like peptide-1 (GLP-1) on the inflammatory damage induced by high glucose(HG) in placental trophoblasts HTR8/SVneo and its molecular mechanism.Methods:Trophoblasts HTR8/SVneo cells were cultured and divided into low glucose(LG) group treated with low glucose (5 mmol/L), HG group treated with high glucose (25 mmol/L), GLP-1 group treated with high glucose combined with GLP-1, miR-137+ GLP-1 group treated with high glucose combined with GLP-1 after the transfection of miR-137 mimic, miR-137 mimic group transfected with miR-137 mimic, negative control (NC) mimic group transfected with NC mimic, and miR-137 inhibitor group transfected with miR-137 inhibitor, NC inhibitor group transfected with NC inhibitor. Apoptotic rate, expression of miR-137 and IL-6 were measured.Results:The apoptotic rate and the expression levels of miR-137 and IL-6 in HG group were significantly higher than those in LG group. The apoptotic rate and the expression levels of miR-137 and IL-6 in GLP-1 group were significantly lower than those in HG group. The apoptotic rate and the expression levels of miR-137 and IL-6 in miR-137+ GLP-1 group were significantly higher than those in GLP-1 group. The apoptotic rate and the expression level of IL-6 in miR-137 mimic group were significantly higher than those of NC mimic group, the apoptotic rate and the expression level of IL-6 in miR-137 inhibitor group were significantly lower than those in the NC inhibitor group.Conclusion:GLP-1 is able to alleviate the inflammation injury of HTR8/SVneo induced by high glucose through the miR-137/IL-6 pathway.

Objective To investigate the clinical efficacy of uterine artery embolization (UAE) for the treatment of cesarean scar pregnancy compared with gelatin sponge strip and gelatin sponge particles as an embolic agent.Methods A retrospective study was performed of 94 consecutive patients with a diagnosis of cesarean scar pregnancy, and they were divided into two groups randomly.The embolic agent in experimental group was gelatin sponge strip and gelatin sponge particles were used in control group.All the cases underwent curettage operation after UAE.The mean amount of bleeding loss during curettage operation, abdominal pain degree after UAE procedure, UAE costs and time of recovery to the normal level of blood β-human chorionic gonadotropin (β-HCG) were compared between two groups.Results The mean amount of bleeding loss during curettage operation and time of recovery to the normal level of blood β-HCG were no statistical differences compared with the two groups, but the abdominal pain degree after UAE procedure and UAE costs in experimental group were lower than in control group, there were significant statistical differences compared with the two groups.Conclusion Gelatin sponge strip as an embolic agent in the UAE procedure of cesarean scar pregnancy could reduce post-operative pain and the cost, which is worthy of clinical promotion.
